When you're done making changes, you can use
npm version patch
to update the version of the package. Then, push all your changes, go to this repo on github, and create a new release.
Whenever you create a new release in this repo, a new github package will be published.
Simply npm install the package like you would any other package.
Here are some references for how this was setup: https://docs.github.com/en/packages/quickstart
